I Took the TinySA Ultra+ ZS407 RF Hunting in an RV Park… Here’s What Happened

In this video, I take a hands-on look at the TinySA Ultra+ ZS407 spectrum analyzer from SeeSii — a compact, powerful RF tool with frequency coverage up to 7.3 GHz. We compare it with previous TinySA models, test real-world RFI at an RV park, and explore how well it integrates with field-ready cases and accessories. This isn’t just a spec rundown — I take the ZS407 out for a spin, track down sources of noise, and evaluate how quiet (or not) a full-time RV setup really is. I also show off the accessories, cases, attenuators, and setup tips that make this analyzer a must-have for RF hobbyists and ham radio operators. 🧰 In This Video: • What’s new in the TinySA Ultra+ ZS407 vs other TinySA models • Field tests: RFI hunting in an RV park using spectrum scans and waterfall display • Attenuator setup for safe signal testing (including 40 dB + 20 dB stack) • Case and accessory walkthrough: mesh bags, 3D printed organizers, DC blocks, and more • Measuring RF noise from charge controllers, LED lights, trucks, and RV electronics • TinySA as a signal generator and sensitivity test tool • Advice on avoiding clones and where to buy safe, legit units 🛒 Affiliate Links — Gear Featured in This Video: Discount,10% off code: X5T6VTAS Expire Date: 2025-05-07 23:59PDT 👉 TinySA Ultra+ ZS407: https://go.temporarilyoffline.com/x74s4q 👉 TinySA Ultra+ ZS406: https://go.temporarilyoffline.com/4i8lfw 👉 TinySA Ultra: https://go.temporarilyoffline.com/4i8lfw 👉 TinySA (Starter): https://go.temporarilyoffline.com/jhkdy4 👉 3d Printed TinySA Ultra Case: https://go.temporarilyoffline.com/snupgw (choose "Ultra") 👉 3d Printed TinySA Case: https://go.temporarilyoffline.com/snupgw (choose "Basic") 👉 3d Printed NanoVNA, NanoVNA-H, NanoVNA-H4 Kit: https://go.temporarilyoffline.com/izgk7m 👉 Single TinySA Ultra Case: https://go.temporarilyoffline.com/du2ym7 👉 TinySA+:NanoVNA Case: https://go.temporarilyoffline.com/xaztvc 👉 Small Mesh Bags: https://go.temporarilyoffline.com/1n1eq9 👉 40db Attenuator: https://go.temporarilyoffline.com/d0y6d7 👉 20db (cute) Attenuators: https://go.temporarilyoffline.com/maws3h 👉 DC Block: https://go.temporarilyoffline.com/yt1vo5 👍 Help me hit my goal of 100K subscribers this year — click Subscribe and be part of the journey! #TinySA #TinySAUltra #ZS704 #SpectrumAnalyzer #HamRadio #RFTestEquipment #NanoVNA #RFI #RVlife #TemporarilyOffline Click the 👍 Like Button, 🤡 Leave a Comment, ❤️ Subscribe 👉 Support The Channel 👈 ❤️ Patreon: https://www.patreon.com/temporarilyoffline 📺 Youtube Memberships: https://www.youtube.com/temporarilyof... 💸 Tip Jar: https://paypal.me/temporarilyoffline 🛒 Amazon Link: https://www.amazon.com/shop/temporarilyoff... 👉 Use Code TO15 for $15 off at Radioddity: https://www.radioddity.com?ref=bpajyqft 🖍️ How I make my Thumbnails: https://partner.canva.com/c/3622632/647168... 👉 Fun Stuff 👈 🫵 We want YOU on TOADs Discord: https://discord.gg/97tkMEc 🕊️ Twitter: https://twitter.com/KiloMike9Golf 😸 Github: https://github.com/TemporarilyOffline Where possible, all links are affiliate links, this youtube thing is an expensive endeavor and every little bit helps.
